If an extension is busy when you call it, you can request a callback when the extension is available. When you receive a callback, a call is placed to the previously-busy extension. You can only request a single callback at a time.
Request a Callback
- Press the TRANS softkey or the Transfer button.
- Enter 508 (feature code for Callback).
Respond to a Callback
- When the Call Back Alert rings, lift the handset or press the Speaker button.
Cancel a Callback
- While a callback is still outstanding, press 509 to cancel it.
